NewsPenn researchers create AI tool to speed antibiotic discovery
Researchers have developed a novel, AI-powered method for turning promising but imperfect antibiotic candidates into more potent ones. ApexGO starts with a small number of imperfect candidates and improves them step by step, using a predictive algorithm to evaluate each modification and guide the next.

NewsThe fog is alive - with tiny helpers
What if fog isn’t just misty air, but a living ecosystem? This question hung over cloud researcher Thi Thuong Thuong Cao. As a PhD student at Arizona State University, her curiosity led her from knocking on the doors of microbiologists and chemists, to sampling fog before sunrise in Pennsylvania, to ...

NewsNew health security operations center will monitor infectious disease risks during this summer’s World Cup gatherings
With millions of soccer fans set to descend on North America for the 2026 FIFA World Cup, experts from Georgetown University and MedStar Health have launched a pioneering Health Security Operations Center (HSOC) to monitor infectious disease transmission and mitigate global health risks.

NewsResearchers develop AI tool to predict E. coli contamination in waterways
A new artificial intelligence framework will alert water managers to E. coli contamination risk before anyone falls sick. The AI-powered predictive modeling framework uses environmental and hydrometeorological data to provide early warnings of contamination in recreational waterways.

NewsNew reactor design produces renewable methane from carbon dioxide
A new reactor design efficiently converts carbon dioxide and renewable electricity into methane while scaling the system up by roughly an order of magnitude. It demonstrated that microbial electrosynthesis systems can be expanded beyond laboratory-scale devices while maintaining high energy efficiency and methane production rates.

NewsResearchers develop promising drug candidate for control and elimination of malaria
Researchers have developed a novel chemical compound that shows promise for the treatment and prevention of malaria, one of the world’s deadliest diseases. T111 has the potential to become a single-encounter malaria drug that would simplify treatment and prevent relapses that drive ongoing transmission.

NewsAndelyn Biosciences launches LVV Curator® Platform
Andelyn Biosciences has announced the launch of its LVV Curator® Platform, a standardized lentiviral vector (LVV) manufacturing solution built on the same proven modular approach that supports clinical and commercial adeno-associated virus (AAV) programs.

NewsFDA approves early warning system for sepsis
An early warning system for sepsis, one of the deadliest infections for hospital patients, has been approved for use by the FDA, one of the first AI-based medical tools to get clearance. The tool detects sepsis hours faster than doctors and has reduced deaths by nearly 20%.

NewsStudy reveals how strawberries and raspberries were ambushed by fungal parasites
Plant diseases often arise when the pathogens that cause disease are introduced into new territories where native plants don’t recognize the pathogen and therefore may have minimal defenses against it. But how often does the reverse happen?

NewsSelf-renewing bacteria offer new hope for heavy metal cleanup
Scientists have revealed a powerful bacterial defense strategy against Cd toxicity. The team found that Stenotrophomonas sp. H225 sheds Cd-laden cell wall fragments and rebuilds new protective layers through a process involving the mtgA gene.

NewsWhat the Andes hantavirus outbreak reveals about pandemic risk
The outbreak of Andes hantavirus aboard the international MV Hondius cruise ship underscores how little scientists still know about the viruses circulating silently in wild rodent populations before they spill into humans.

NewsStudy reveals common mutation linked to autoimmune diseases may protect people from viral infections
New research shows a “risk gene” linked to higher odds of developing autoimmune diseases such as diabetes or lupus may also provide a survival advantage fighting viral infections like coronavirus. The gene PTPN22 carries a mutation, 1858C>T (R620W), found in roughly one in 10 people in North America.

NewsData hidden in tuberculosis screening tests sheds light on patients’ overall mortality
Researchers have uncovered a tool to study immune function of larger populations of patients, using a lab test that physicians already use regularly: tuberculosis screening tests called interferon gamma release assays (IGRAs). It could indicate how well an immune system can mount a response to an array of threats.

NewsResearchers track the mutations that allow HIV-1 to escape broadly neutralizing antibodies
Scientists have established the most comprehensive view to date of how HIV-1 can escape broadly neutralizing antibodies. They have discovered viral mutations that make HIV-1 strains resistant to two bNAbs, 3BNC117 and 10-1074.

NewsThawing Arctic soil awakens only half of soil microbes, new study reveals
A study shows that even after months of thawing, around half of the microorganisms in High Arctic soils remain dormant. This challenges the assumption that warming uniformly boosts microbial activity and carbon release from thawing permafrost.

NewsAnti-CRISPR stops the protein assembly line in bacteria
Bacteria fend off invading viruses with molecular scissors that slice up viral DNA, but viruses can fight back with a molecular trick that stops the scissors from ever being made. A viral “anti-CRISPR” protein sits on the ribosome and jams it as a CRISPR protein named Cas12 begins to form.

NewsMouse study suggests high-fat diets during pregnancy worsen severe GI illness in preterm babies
A new mouse study suggests a link between a high-fat prenatal diet and induction of potentially deadly symptoms of necrotizing enterocolitis (NEC) in premature babies.

NewsScientists take crucial step in developing world’s first measles treatment
Scientists have characterized human antibodies capable of neutralizing measles virus. These antibodies bind to key sites on measles virus and prevent the virus from entering host cells.

NewsGlobal outbreaks may fuel violence against women — but most cases go unmeasured
Violence against women and girls may increase during infectious disease outbreaks — as economic strain, isolation and disrupted services reshape daily life — yet those impacts remain largely unmeasured, according to a new study.
